title: [Atypical sciatica].
abstract: A 46-year old patient had suffered from progressive nocturnal sciatica and motor weakness of the left lower extremity for three years. The physical examination revealed a discrete neurologic deficit of the left L5 and S1 root. By CT a small presacral mass between the L5 and S1 roots was found. During the CT-guided fine needle puncture the patient felt an electrifying pain radiating into the left lower extremity. The cytomorphological examination showed benign mesenchymal cells, indicative of a neurinoma. Since progredient neurological deficit is to be expected, exstirpation of the compressing tumor is the therapy of choice. Our patient however decided to postpone the operation because of only mild symptoms.
